• Features:

SPEED:

First language acquisition is remarkable for the speed with which it takes place.

SOPHISTICATED LANGUAGE USER:Long before a child starts school, he or she

has become an extremely sophisticatedlanguage-user, operating a system for self-

expression and communicationthat no other creature, or computer, comes

close to matching.

OVERT INSTRUCTIONS:

In addition to the speed of acquisition, the fact that it generally occurs, without overt instruction, for all children, regardless of great differences in their circumstances, provides strong support for the idea that there is an innate predisposition in the humaninfant to acquire language.

SPECIAL CAPACITY:We can think of this as a special capacity for language with which each newborn child is endowed. By itself, however, this inborn language capacity is not enough.

Basic requirements

INTERACTION:

During the first two or three years of development, a child requires interaction with other language-users in order to bring this general language capacity into operation with a particular language such as English.

LANGUAGE USING ENVIRONMNET:

We have also identified the importance of cultural transmission, meaning that the language a child learns is not genetically inherited, but is acquired in a particular language-using environment.

PHYSICAL CAPABILITY:

The child must also be physically capable of sending and receiving sound signals in a language. All infants make ‘cooing’ and ‘babbling’ noises during their first year, but congenitally deaf infants stop aftCer about six months

EXPOSURE TO TV, etc:

One reported case has demonstrated that, with deaf parents who gave their normal-hearing son ample exposure to TV and radio programs, the boy did not acquire an ability to speak or understand English. What he did learn very effectively, by the age of three, was the use of American Sign Language – the language he used to interact with his parents.

OPPORTUNITY:

The crucial requirement appears to be the opportunity to interact with others via language.

The acquisition scheduleAll normal children develop language at roughly the same time, along much the same schedule. Since we could say the same thing for sitting up, standing, walking, using the hands and many other physical activities, it would seem that the language acquisition schedule has the same basis as the biologically determined development of motor skills. This biological schedule is tied very much to the maturation of the infant’s brain.

LINGUISTIC ‘INPUT’

We could think of the child as having the biological capacity to cope with distinguishing certain aspects of linguistic ‘input’ at different stages during the early years of life.

For example:At one month an infant is capable ofdistinguishing between sounds such as [ba] and [pa].

CONSTATNT TYPE OF ACQUISITION:

What this acquisition capacity then requires is a sufficiently constant type of ‘input’ from which thebasis of the regularities in a particular language can be worked out. In this view, young children are seen as actively acquiring the language by identifyingthe regularities in what is heard and then applying those regularities in what they say.

Caregiver speechUnder normal circumstances, human infants are

certainly helped in their language acquisition by the typical behavior of older children and adults in the home environment.

ADDRESSING THE LITTLE CHILDREN:

Adults such as mom, dad and the grandparents tend not to address the little creature before them as if they are involved in normal adultto-adult conversation. There is not much of this: Well, John Junior, shall we invest in blue chip industrials, or would grain futures offer better short-term prospects? However, there does seem to be a lot of this: Oh, goody, now Daddy push choo choo? The characteristically simplified speech style adopted by someone who spends a lot of time interacting with a young child is called caregiver speech.

FREQUENT USE OF QUESTION:

Salient features of this type of speech (also called ‘motherese’ or ‘childdirected speech’) are the frequent use of questions, often using exaggeratedintonation, extra loudness and a slower tempo with longer pauses.

CONVERSATIONAL STRUCTURE:CONVERSATIONAL STRUCTURE:

Built into a lot of caregiver speech is a type of conversational structure that seems to assign an interactive role to the young child even before he or she becomes a speaking participant.

SIMPLE SENTENCE STRUCTRESCaregiver speech is also characterized by simple

sentence structures and a lotof repetition

Stages Stages in the acquisition process

Cooing and babbling

The earliest use of speech-like sounds has been described as cooing. During the first few months of life, the child gradually becomes capable of producing sequences of vowel-like sounds, particularly high vowels similar to [i] and [u].

FOURTH MONTHS OF AGE:

By four months of age, the developing ability to bring the back of the tongue into regular contact with the back of the palate allows the infant to create sounds similar to the velar consonants [k] and [g], hence the common description as ‘cooing’ or ‘gooing’ for this type of production.

FIVE MONTHS OF AGE:FIVE MONTHS OF AGE:

Speech perception studies have shown that by the time they are five months old, babies can already hear the difference between the vowels [i] and [a] and discriminate between syllables like [ba] and [ga].

SIX AND EIGHT MONTHS:SIX AND EIGHT MONTHS:

Between six and eight months, the child is sitting up and producing a number of different vowels and consonants, as well as combinations such as ba-ba-ba and ga-ga-ga. This type of sound production is described as babbling.

NINE TO TEN MONTHS:

In the later babbling stage, around nine to ten months, there are recognizable intonation patterns to the consonant and vowel combinations being produced, as well as variation in the combinations such as ba-ba-da-da. Nasal sounds also becomemore common and certain syllable sequences such as ma-ma-ma and da-dada are inevitably interpreted by parents as versions of ‘mama’ and ‘dada’ and repeated back to the child.

TENTH AND ELEVENTH MONTHS:TENTH AND ELEVENTH MONTHS:

As children begin to pull themselves into a standing position during the tenth and eleventh months, they become capable of using their vocalizations to express emotions and emphasis.

The one-word stage

Between twelve and eighteen months, children begin to produce a variety of recognizable single-unit utterances. This period, traditionally called the oneword stage, is characterized by speech in which single terms are uttered for everyday objects such as ‘milk’, ‘cookie’, ‘cat’, ‘cup’ and ‘spoon’ (usually

pronounced [pun]).

HOLOPHRASTIC:HOLOPHRASTIC:

We sometimes use the term holophrastic (meaning a single form functioning as a phrase or sentence) to describe an utterance that could be analyzed as a word, a phrase, or a sentence.

SUCH UTTERANCES:SUCH UTTERANCES:

While many of these holophrastic utterances seem to be used to name objects, they may also be produced in circumstances that suggest the child is already extending their use.

The two-word stage

Depending on what we count as an occurrence of two distinct words used together, the two-word stage can begin around eighteen to twenty months, as the child’s vocabulary moves beyond fifty words.

By the time the child is two years old, a variety of combinations, similar to baby chair, mommy eat, cat bad,will usually have appeared

RECEIVING FEEDBACK:RECEIVING FEEDBACK:

The child not only produces speech,but receives feedback confirming that the utterance

worked as a contribution tothe interaction.

Telegraphic speechBetween two and two-and-a-half years old, the

child begins producing a large number of utterances that could be classified as ‘multiple-word’ speech.

STRINGS OF WORDS:This is characterized by strings of words (lexical

morphemes) in phrases or sentences such as this shoe all wet, cat drink milk and daddy go bye-bye.

SENTENCE BUILDING CAPACITY:SENTENCE BUILDING CAPACITY:

The child has clearly developed some sentence-building capacity by this stage and can get the word

order correct.

GRAMMATICAL INFLECTIONS:While this type of telegram-format speech is beingproduced, a number of grammatical inflections begin

to appear in some of the word-forms and simple prepositions (in, on) are also used.

TWO AND A HALF-YEARS:TWO AND A HALF-YEARS:

By the age of two-and-a-half years, the child’s vocabulary is expanding rapidly and the child is initiating more talk while increased physical activity includes running and jumping.

BY THREE:the vocabulary has grown to hundreds of words and

pronunciation has become closer to the form of adult language.

The acquisition process

As the linguistic repertoire of the child increases, it is often assumed that the child is, in some sense, being ‘taught’ the language.

NO INSTRUCTIONS:For the vast majority of children, no one provides

any instruction on how to speak the language.  

TRYING OUT CONSTRUCTIONS AND TRYING OUT CONSTRUCTIONS AND TESTING:TESTING:

The child’s linguistic production appears to be mostly a matter of trying out constructions and testing whether they work or not.

PROCESS OF IMITATING:PROCESS OF IMITATING:

It is simply not possible that the child is acquiring the language principally through a process of imitating adult speech. Certainly, children can be heard to repeat versions of what adults say on occasion and they are clearly in the process of adopting a lot of vocabulary from the speech they hear.

ADULT CORRECTION:ADULT CORRECTION:

It is also unlikely that adult ‘corrections’ are a very effective determiner of how the child speaks.

ACTUAL USE OF SOUND AND WORD COMBINATION:

One factor that seems to be important in the child’s acquisition process is the actual use of sound and word combinations, either in interaction with others or in word play, alone

Developing morphology

By the time a child is two-and-a-half years old, he or she is going beyond telegraphic speech forms and incorporating some of the inflectional morphemes that indicate the grammatical function of the nouns and verbs used. The first to appear is usually the -ing form in expressions such as cat sitting and mommy reading book.

REGULAR PLURALS:REGULAR PLURALS:

The next morphological development is typically the marking of regular plurals with the -s form, as in boys and cats. The acquisition of the plural marker is often accompanied by a process of overgeneralization.

OVERGENERALIZATION:OVERGENERALIZATION:

The child overgeneralizes the apparent rule of adding -s to form plurals and will talk about

foots and mans.

When the alternative pronunciation of the plural morpheme used in houses (i.e. ending in [-əz]) comes into use, it too is given an overgeneralized

application and forms such as boyses or footses can be heard.

IRREGULAR PLURALS:IRREGULAR PLURALS:

At the same time as this overgeneralization is taking place, some children also begin using irregular

plurals such as men quite appropriately for a while, but then try out the general rule on the forms, producing expressions like some mens and two feets, or even two feetses.

FORMS OF VERB ‘TO BE’FORMS OF VERB ‘TO BE’

At about the same time, different forms of the verb ‘to be’, such as are and was, begin to be used. The appearance of forms such as was and, at about the

same time, went and came should be noted. These are irregular past-tense forms that we would not expect to hear before the more regular forms.

Developing syntaxSimilar evidence against ‘imitation’ as the basis of

the child’s speech production has been found in studies of the syntactic structures used by young children. One child, specifically asked to repeat what she heard, would listen to an adult say forms such as the owl who eats candy runs fast and then repeat them in the form owl eat candy and he run fast. It is clear that the child understands what

the adult is saying. She just has her own way of expressing it.

DEVELOPMENT OF SYNTAX:DEVELOPMENT OF SYNTAX:

There have been numerous studies of the development of syntax in children’s speech. We will look at the development of two structures that seem to be acquired in a regular way by most English-speaking children. In the formation of questions and the use of negatives, there appear to be three identifiable stages.

THE AGES: at which children go through these stages can vary quite a bit, but the general pattern seems to be that stage 1 occurs between 18 and 26 months, stage 2 between 22 and 30 months, and stage 3 between 24 and 40 months.

Forming questionsIn forming questions, the child’s first stage has two

procedures. Simply add a Wh-form(Where,Who) to the beginning of the expression or utter the expression with a rise in intonation towards the end, as in these examples:

Where kitty? Doggie?Where horse go? Sit chair?

IN THE SECOND STAGE: more complex expressions can be formed, but the rising intonation strategy continues to be used. It is noticeable that more Wh-forms come into use, as in these

examples:What book name? You want eat?Why you smiling? See my doggie?

IN THE THIRD STAGE: the required inversion of subject and verb in English questions appears (I can go→Can I go?), but the Wh-questions do not always undergo the required inversion.

Forming negatives

In the case of negatives, STAGE 1 seems to involve a simple strategy of putting no or not at the beginning, as in these examples:

no mitten not a teddy bear no fall no sit there

In the SECOND STAGE, the additional negative forms don’t and can’t appear, and

with no and not, are increasingly used in front of the verb rather than at thebeginning of the sentence, as in these examples:

-He no bite you I don’t want it-That not mommy You can’t dance

The THIRD STAGE sees the incorporation of other auxiliary forms such as didn’t and won’t while the typical stage 1 forms disappear. A very late acquisition is the negative form isn’t, with the result that some stage 2 forms (with not instead of isn’t) continue to be used for quite a long time, as in the

examples:I didn’t caught it He not taking itShe won’t let go This not ice cream

Developing semantics

The anecdotes that parents retell about their child’s early speech (to the intense embarrassment of the grown-up child) usually involve examples of the strange use of words. Having been warned that flies bring germs into the house, one child was asked what “germs” were and the answer was “something the flies play with”. It is not always possible to determine so precisely the meanings that children attach to the words they use.

HOLOPHRASTIC STAGE:

It seems that during the holophrastic stage many children use their limited vocabulary to refer to a large number of unrelated objects.

OVEREXTENSION:One child first used bow-wow to refer to a dog and then to a fur piece with glass eyes, a set of cufflinks and even a bath thermometer. The word bow-wow seemed to have a meaning like ‘object with shiny bits’. Other children often extend bow-wow to refer to cats, cows and horses. This process is called overextension and the most common pattern is forthe child to overextend the meaning of a word on the basis of similarities of shape, sound and size, and, to a lesser extent, movement and texture.

SIMILARITIES OF TEXTURE:SIMILARITIES OF TEXTURE:

Apparently due to similarities of texture, the expression sizo was first used by one child for scissors, and then extended to all metal objects.

DEVELOPMENT OF SEMANTICS:DEVELOPMENT OF SEMANTICS:

The semantic development in a child’s use of words is usually a process of overextension initially, followed by a gradual process of narrowing down the application of each term as more words are learned.

COMPLETION:COMPLETION:

Despite the fact that the child is still acquiring aspects of his or her native language through the later years of childhood, it is normally assumed that, by the age of five, the child has completed the greater part of the basic language acquisition process

L 2 LEARNING:L 2 LEARNING:

According to some, the child is then in a good position to start learning a second (or foreign) language. However, most people don’t start

trying to learn another language until much later.

THE QUESTION that always arises is: if first language acquisition was so straightforward and largely automatic, why is learning a second language so difficult? The next presenters will answer this particular question.
